CI: Add native Windows VS2019 build

Adds a native build of Mesa using Meson with the Visual Studio 2019
toolchain on a Windows host.

Though Docker is supported on Windows, Docker-in-Docker is not possible,
nor are podman and skopeo available. We handle this by creating the
container from a shell-executor Windows machine, which gives us a native
PowerShell that we can execute Docker from. This attempts to do the same
copy-from-upstream-or-create-if-not-exists optimisation as the
ci-templates do for our Linux builds, albeit open-coded in PowerShell.

gallium/util: Add back (and rename) util_float_to_half implementation

This implementation was removed by 8b8af6d3 ("gallium/util: Switch
util_float_to_half to _mesa_float_to_half()'s impl.")
It was not actually broken, but _mesa_float_to_half() implements
round-to-nearest-even, whereas util_float_to_half() implemented
round-to-zero. So rename it appropriately.
GL actually never cares about rounding (except a broken piglit test),
however d3d10 very much does and requires RTZ for float to half
conversion. Moreover, apparently at least radeon gpus actually always
do RTZ when doing RT writes (and I'd suspect for shader image writes
as well). Hence it seems appropriate to hook up this rtz function to
the format instead. This will cause llvmpipe and softpipe to use rtz
rounding for clears with half float formats, and softpipe would use rtz
behavior for rt writes as well (llvmpipe has that hardcoded), not sure
if "real" hw drivers hit this function for much.
(For shader opcodes would still need to figure out what rounding to use
appropriately, but this is a question for another day.)
Note should probably unify with _mesa_float_to_float16_rtz. Unclear at
this point which one is better, so just restore previous function here.

glsl/lower_precision: Lower builtins depending on arguments

When an ir_call is encountered that invokes a builtin, it will now try
to generate a lowered version of the builtin. This only happens if all
of the arguments to the function are lowerable. Previously the builtin
would be inlined before the lowering pass is invoked and then the
implementation would be lowered as a consequence of the pass. However
this causes problems if the builtin has multiple arguments and the
implementation has operations on only a few of the arguments before
combining it with the others. In that case the entire builtin should
only be lowered if all of the arguments are lower precision. The
previous approach would end up lowering only parts of the
implementation.

The lowered implementations are cached in a hash table in case they can
be reused.

be useful to be able to insert some handling for the precision lowering
pass before the inlining. This needs to happen because the precision
of the operations in the inlined implementation depends on the highest
precision of all of the arguments to the call.

freedreno/ir3: enable nir_opt_loop_unroll on a6xx

If precision lowering happens at GLSL IR, loop_analysis at IR doesn't
work as expected since it can't handle things like:

"(expression bool < (expression float16_t f2fmp (var_ref ndx) ) (constant float16_t (1.000000)) )"

So we'd rather do this optimization at the NIR stage.

glsl: Add an IR lowering pass to convert mediump operations to 16-bit

This works by finding the first rvalue that it can lower using an
ir_rvalue_visitor. In that case it adds a conversion to float16
after each rvalue and a conversion back to float before storing
the assignment.

Also it uses a set to keep track of rvalues that have been
lowred already. The handle_rvalue method of the rvalue visitor doesn’t
provide any way to stop iteration. If we handle a value in
find_precision_visitor we want to be able to stop it from descending into
the lowered rvalue again.

Additionally this pass disallows converting nodes containing non-float.
The can_lower_rvalue function explicitly excludes any branches
that have non-float types except bools. This avoids the need to have
special handling for functions that convert to int or double.

v2. Adds lowering for texture samples

v3. Instead of checking whether each node can be lowered while walking the
tree, a separate tree walk is now done to check all of the nodes in a
single pass. The lowerable nodes are added to a set which is checked
during find_precision_visitor instead of calling can_lower_rvalue.

v4. Move the special case for temporaries to find_lowerable_rvalues. This
needs to be handled while checking for lowerable rvalues so that any
later dereferences of the variable will see the right precision.

v5. Add an override to visit ir_call instructions and apply the same
technique to override the precision of the temporary variable in the
same way as done for builtin temporaries and ir_assignment calls.

v6. Changes the pass so that it doesn’t need to lower an entire subtree in
order do perform a lowering. Instead, certain instructions can be
marked as being indepedent of their child instructions. For example,
this is the case with array dereferences. The precision of the array
index doesn’t have any bearing on whether things using the result of
the array deref can be lowered.

Now, only toplevel lowerable nodes are added to the lowerable_rvalues
instead instead of additionally adding all of the subnodes.

It now also only needs one hash table instead of two.

v7. Don’t try to lower sampler types. Instead, the sample instruction is
now treated as an independent point where the result of the sample can
be used in a lowered section. The precision of the sampler type
determines the precision of the sample instruction. This also means
the coordinates to the sampler can be lowered.

v8. Use f2fmp instead of f2f16.

v9.  Disable lowering derivatives calcualtions, which might not work
properly on some hw backends.
